Scalar, obviously.
How do you figure that? (Not a criticism: I'd really like to understand your
thought process here so I can assess the relative DWIMity of the two
alternatives).

Piers posed the following puzzles:
@ary[0] = foo() # scalar
Yes.
@ary[1,2] = foo() # list context
Yes.
@bar = 1;
@ary[@bar] = foo() # ? probably list or maybe scalar...
List. With an explicit array as index, it's definitely a (one-element) slice.
@bar = (1,2);
In the following code fragment, what context is foo() in?
@ary[0] = foo()
the following code
@ary= foo()
obviously evaluates @foo in a list context, but in the first I'm no
longer sure.

The short answer is scalar context. The long answer is below. Note
that the long answer is only the way I think of it. You may think
differently.
I like to think of it as 'one context'.
In the following code fragment, what context is foo() in?
@ary[0] = foo()
Scalar context. @ary[0] is a single element of @ary.
To call foo() in list context use any of the following:
(@ary[0]) = foo(); # Assign @ary[0] the first element returned

Hm, thats a change from perl5. In perl5 that would assign the number of
elements returned from foo(). Is there a good reason for this change ?
Firstly, Larry may have to rule on which behaviour actually *is* invoked
